Alot of suspension kits dont cater for a shorter stroke at all! The uprated shocks they make are the exact same length as the OEM items, and so the only way to lower the car and still have the spring stay captive when its not under compression is to put all those useless coils on them. Rally boys dig the full length for their needs and they can then keep the car fully jacked up and use all of the shock if they put their own springs on there.. But for drift and circuit...
